Maxim 7219 - Real and Fake compared

Yep, mine are the fakers for sure. Except for the ones I got directly from Maxim, those are just like the "real" photos. Though, and I must stress this, the "fakes" do work for me.

I also have some SOP "MAX7219s". Any information in determining if these are real or not? Typical auction:

Almost certainly fake, I would think.

Thanks for the photos, that was great.
